Despite what some may say about Shell and whether they paid to have it there, I’ve worked with multiple tuners on several platforms including BMW, and many of them swear by Shell. They say it’s the most knock-resistant and allows for way more aggressive timing than Shell’s counterparts. Sunoco has really good fuel too I’ve heard.
